Does Red Hat in-place OS upgrade corrupt GitLab CE?

I have a GitLab Community Edition v16.10.5 instance running on Red Hat Linux 7.9. I haven’t been able to migrate this instance using the prescribed GitLab backup and restore methods. Details on those woes can be found here.

I have started manually migrating users and groups to a new instance, and users will have to manually move their code. This will be an intensive process.

Has anyone had luck using Red Hat’s in-place upgrade process (leapp)? This would solve my issue until I’m forced to upgrade to RH9.
